HC Deb 19 June 1963 vol 679 c74W
56. Mr. Godman Irvine

asked the Minister of Transport whether, in view of the continued interference with television and radio reception, he will refuse in future to issue a certificate of roadworthiness to a motor vehicle not fitted with a suppressor.

Mr. Marples

No. I do not consider that the vehicle testing scheme could suitably be used for this purpose.
